Detailed Answer:
Dear Madam ,
Thank you for posting your query on XXXXXXX
Well looking into your problem I would like to tell you that it will not be possible to point out one diagnosis for this . There can be so many causes for such rash .
You need to see a dermatologist for this because without physical examination of rash it is impossible to opine as it is very important to see the size , colour , flaking present or not , elevated or not .
One thing is to check your plataelet count to rule out thrombocytopenia and your allergic profile . Kindly see a dermatologist as soon as possible .
Take care.
